Why Is My Heat Pump Running But Not Cooling Properly?
Your heat pump often runs but won’t cool because of a clogged filter, dirty coils or fan, incorrect thermostat or fan settings, blocked registers, a broken belt, or loose parts. Rising electric bills, odd smells, or frequent cycling also point to needed service. Boulden Brothers offers same-day heat pump repair in Newark, DE with up-front, no-surprise pricing.
Quick checks:
- Replace the air filter.
- Set thermostat to Cool and fan to Auto.
- Open and clear all registers.
